[b]我想用java做一个web services。请问该怎么做？[/b]

给点提示。。。谢谢。。。

我好像知道个Axis。但是看了看好像不怎么.好..请问还有什么其他的好办法写web services么？

Answer 1

用axis开发 很简单的主要就是一份wsdd文件
例如server-config.wsdd
[code="java"]

<!-- 要发布的方法全在这个类里 -->



[/code]

要发布的webService类的方法
[code="java"]

package com.dreamtech.webService;

import javax.xml.rpc.ServiceException;

import clients.WebServiceService;
import clients.WebServiceServiceLocator;
import clients.WebService_PortType;

import com.dreamtech.bo.Equipment;
import com.dreamtech.dao.Dao;

public class WebService {
//初次刷卡时 写入数据 并返回状态
public String save(String uId, String equipmentId){
String state = null;
Dao dao = Dao.getDaoInstance();

Equipment em = new Equipment();
em.setEquipmentId(equipmentId);
em.setUid(uId);
em.setState("0");
try {
dao.saveObject(em);
em = (Equipment)dao.findSingleObj("from Equipment e where e.uid='"+uId+"' and e.equipmentId='"+equipmentId+"'");
state = em.getState();
return state;
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return "数据不存在，请联系管理员";
}

//离开时 更新数据 并返回状态
public String updateState(String uId, String equipmentId){
    Dao dao = Dao.getDaoInstance();     
    String state = null;
    Equipment em = new Equipment();
    try {
        em = (Equipment)dao.findSingleObj("from Equipment e where e.uid='"+uId+"' and e.equipmentId='"+equipmentId+"'");
        em.setState("1");
        dao.updateObject(em);
        em = (Equipment)dao.findSingleObj("from Equipment e where e.uid='"+uId+"' and e.equipmentId='"+equipmentId+"'");
        state = em.getState();
        return state;
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }
    return "数据不存在，请联系管理员";
}

[/code]
在web.xml里加入
[code="java"]
AxisServlet

org.apache.axis.transport.http.AxisServlet



AdminServlet

org.apache.axis.transport.http.AdminServlet
100

<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/servlet/AxisServlet</url-pattern>
</servlet-mapping>  
<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>*.jws</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>AxisServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
